About the title
According to an ancient legend, Queen Louhan was a cruel ruler, and the leader of the Humo people killed her with a sacred sword. This led to the fall of her kingdom. Nevertheless, the queen's loyal red priestess hid her body in the black tower of Lop Nur, guarded by a black serpent until she comes back to life. No one knows what happened to the red priestess, but her drum, found by Hu Bayi and his friends, confirms that the legend is true.
